The Structure Of A Bolted Parallel Groove Clamp

The bolted connector aluminium pg clamp adopts a plate-to-plate structure and is made of aluminum alloy.  It uses the tightening pressure of bolts to secure the connecting wires between upper and lower grooved plates, completing the connection.  The pressure is transmitted through flat washers and spring washers, providing relatively uniform and constant pressure to the connecting wires. It is detachable after installation and is often used in jumper connections or conductor/ground wire splices at the tension end of the line. To ensure sufficient and uniform pressure on the conductor, the connector bimetal pg clamp generally uses a two-bolt or three-bolt structure, and requires even force when tightening each bolt during installation. Sometimes, to ensure reliable operation, two or three connectors are connected in parallel at equal distances during line construction. The gripping force of the bolted connector blackburn parallel groove clamp on the conductor is approximately 10%-20% of the calculated breaking strength of the conductor.
The bolted equal-diameter connector burndy parallel groove clamp generally only connects conductors of the same diameter. The allowed conductor span usually includes two adjacent sizes, such as the JB-4 connector parallel groove, which is suitable for conductor cross-sections of 185mm2 and 240mm2. Therefore, it adopts a symmetrical design.
The bolted unequal-diameter connector groove clamp allows for continuous connection of conductors within a certain diameter range. It adopts an asymmetrical design, and the pressure plate is designed to be adjustable left and right to ensure that both unequal-diameter conductors receive relatively stable pressure during contact. However, human factors significantly affect the tightening degree of the bolts.
